When do polymer coating during gloves production

Whichever material rubber gloves are made of, they are manufactured in the same basic way. The process starts with hand-shaped ceramic or aluminum molds on a conveyor, which are dipped in wash tanks with hot water and chlorine or bleach and then dried. This dipping gets rid of any potential residue from the previous batch of gloves. Once the molds are cleaned, they must be coated to make the rubber stick. To accomplish this the molds are dipped into a mixture of calcium nitrate solution (which will coagulate the rubber) and calcium carbonate (which is a lubricant to keep the gloves from sticking to the mold too much). A second drying occurs, and then the glove forms dip into tanks of either latex, nitrile, or polyvinyl chloride. This is when the processes begin to differ since the materials must be processed differently.

Latex gloves have their thickness determined by how long they remain in the tank. Once the forms are out, they spin to remove excess rubber and then are washed in hot water and chlorine again. This process removes excess latex and chemicals to lower the severity of any allergic reactions. The forms are then dried and cured using vulcanization, which interlinks the rubber molecules to make the gloves stronger. After a second rinse to remove any more excess latex, the gloves go through a series of brushes that roll (also known as beading) their ends into cuffs. They are then removed using air jets. Once they’re off the molds, the gloves can be tested and shipped.

RF-8848 is a modified acrylic copolymers emulsion, specially used for dipping coating as the inner lining of nitrile gloves. The outstanding characteristics of this product are super soft, excellent chemical stability, high resistance to dinning.
